Thermal Output Vs. Flow Rate Behaviour - DUALSUN M-60-3BBP Serie Manual De Instalación, Uso Y Mantenimiento

2.3.4 Thermal output vs. flow rate behaviour

- For domestic hot water (DHW) applications, the recommended nominal flow rate is 32 L/h/panel.
- For applications towards a thermal discharge, the recommended nominal flow rate is 100 L/h/panel. For
example, towards a swimming pool or geothermal probes.
- For direct pool heating applications, the recommended nominal flow rate is 200 L/h/panel.
